  • The application of analytical model(Archer et al. 1983) to shielding calculations in diagnostic radiology combined with measurements of the broad beam transmission properties of lead, steel, concrete, and plate glass for x-ray tube potential of 60-140 kVp using an x-ray inverter generator and total initial beam filtration sufficient to provide half-valve layer representative of those found in common practice and required by regulatory agencies. Our transmission measurements and numerical fits to the mathematical model of broad beam transmission(Archer et al. 1983) will assist medical or health physicist faced with the task of designing protective barriers for medical diagnostic x-ray facilities.

  • This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their behaviors by measuring the level of self-efficacy and consciousness on the use of radiation, knowledge and attitude on radiation safety management(RSM). The subjects were 235 of the dental hygienists and this study performed a survey 8 May to 17 June, 2011. The survey results were as follows. 1. As a result of comparing the average of the self-efficacy according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to health condition, protection facilities condition. 2. As a result of comparing the average of consciousness about radiation use according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to medical institute type, protection facilities conditions. 3. As a result of comparing the average of the behaviors for RSM according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to monthly income, medical institute type, whether or not education on radiation was conducted, the number of education, education type, and protection facilities condition. 4. As a result of analyzing what factors have an influence on the behaviors for RSM by employing the points of those behaviors as a dependent variable and self-efficacy, consciousness, knowledge and attitude as an independent variable in order to investigate those factors, it turned out that the factors which had a relatively larger influence on the point of behaviors were attitude and self-efficacy by that order(p<0.05). In conclusion, we believe that a variety of programs should be offered to provide knowledge on RSM as a prerequisite for improving the level of RSM behaviors by dental hygienists.

  • By measuring decrease change of the contact angle after microwave plasma treatment on the glass and Al as a scintillator panel sample substrate, the adhesive performance of scintillator panel can be expected to improve. Also resolution and sensitivity of scintillator panel after microwave plasma treatment can be expected to maintain highly.
